Subaru is recalling 100,127 cars in the United States for secondary air-injection pumps that can catch fire, according to filings with the National Highway Traffic Safety Administration.

Only turbocharged versions of the 2007–2009 Legacy and Outback, 2009–2013 Forester, and 2008–2014 Impreza are affected. To be specific, the trims include the Legacy 2.5GT, Outback 2.5XT, Forester 2.5XT, and the Impreza 2.5GT, WRX, and WRX STI.

Also known as the smog pump, the secondary air-injection pump sends air into the exhaust stream directly after the manifold to burn up unwanted hydrocarbons. A faulty relay that controls the air pump may let the pump run continuously, at which point the pump could overheat, melt, and catch fire. In fact, that exact scenario has occurred at least twice between 2013 and 2015, Subaru reported. Before that, Subaru said it had only found fault codes that led to a check engine light, and the company corrected the pump relay problem in production by September 2013. According to Subaru, at that time the company did not investigate a potential for fires. No accidents or injuries have been reported.

Dealers will replace the pump relay at a later date. If your affected Subaru’s check engine light comes on—the only warning of a problem, other than actual smoke—bring it to a dealer sooner than later. Earlier this month, Subaru recalled more than 592,000 cars for windshield-wiper motors that could melt and catch fire.
